Which congruence theorem can be used to prove △WXS ≅ △YZS? Triangles W X S and Y Z S are connected at point S. Angles W X S and S Z Y are right angles. Sides X S and S Z are congruent. SSS ASA SAS HL

Point S makes the two connected angles the same. T both have right angles. And one side of each is congruent. This means you know 2 angles are the same and one side is the same.You would use ASA (Angle, Side, Angle)
